IMPROVED GRATIS-BAR FOR STEAM AND OTHER ENG-INERY.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom 'it may concern Be it known that we, MONROE Monsn and UHA Bans H. MORSE, of Franklin, in the county of Norfolk, and State of Massachusetts, have invented a new and useful Improvement in Firc-Grate Bar; and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the artto make and use the same, reference being bad to the accompanying drawings, forming part of this specification.

This invention relates to a new and useful improvement in grate-bars for furnaces, and consists in a false bar or rider, made in one or more sections, which false bar or rider is most exposed to the heat, and which may readily be removed or renewed,.'the parts being constructed and connected together, as hereinafter more fully described.

In the accompanying drawings Figure 1 represents a longitudinal side view of the grate-bar complete.

Figure 2 is a. longitudinal top or plan view of the rider.

Figure 3 is a topor plan view of the supportinggrate with the rider removed.

Figure 4 is a side view of the rider, showing lugs, by which it is attached to the supporting-bar.

Figure 5 is a cross-section of the rider through the line a: a: of fig. 4.

Similar letters of reference indicate corresponding parts.

A-is the main orsupporting-bar, which is made double, in the usual manner, and supported .at its ends on the front plate and bridge-wall, as usual. On the inner side, between the double bars, there are flanges B, as seen in fig. 3.

0 represents a false bar or rider. This may be made in sections, as seen in the drawing, or in a single piece. When made as represented, the sections are duplicates of each other, tongned and grooved at their ends, as seen, and connected to the main grate at one end by means of a hook-lug, D, (see fig. 5,) which hooks under the flange B. The other end is provided with a lug, E, which fits between the bars of A, and prevents too much lateral movement. The sections are shoved in from the front, one after the other, and set a short distance above the support.- ing-bar, as seen in fig. 1, where the hook and the lug are seen in dotted lines. The parts fit loosely together, so that they are not injuriously affected by the expansion and contraction caused by the heat.

Being most exposed to the intense heat of the fire when the rider (or any one of the sections) burns out,

it may readily be removed and replaced by another.

Thus the grate may be renewed at a trifling expense,

Also, when a coarser or a finer grate is desired, it is only necessary to make a change in the. riders, and the object is accomplished. By this arrangement the free use of the fire-hook is allowed for cleaning the air-spaces of ashes or cinders.

The advantages of this method of constructing grate-bars are many, and must be obvious to all.

Having thus described our invention,

We claim as new, and desire to secure by Letters Pat-ent-- In combination with a grate-bar, the false bar or rider 0, constructed and arranged substantially as and for the purposes described.
